Hello Members,

I am new to linux and i am using RHEL (Linux 2.6.18-371.el5). I have a query: How to send attachments using mailx command?

i have tried:

i. mailx -s "subject" -a "attachment" "recipient" command.
ii. echo|mailx -s ""subject" -a "attachment" "recipient"
iii. uuencode filename | mailx -s "subject" "recipient"

none of these worked for me.
I have gone through different threads in this forum but could not find anything that fits my query.
Could you guys please help me out or maybe point me towards right discussion.
Thanks!

Regards,
Neel

I tried
with a 112 bytes binary attachment, and it worked for me. That is, I was able to send the message and found it, with attachment, in the recipient's mailbox. The mailbox contains:
EDIT: This was on Centos 8, not RHEL 5. Perhaps your version of mailx works differently.

Thanks berndbausch..
But it does not work.
Need other ideas.

Then you need to provide details, such as what you're trying to attach, version of RHEL, what mail system, results of the tests, etc. We need more details than "does not work".

Depending on what you're trying to send, you may have to use mime64, break it up into a multi-part message, etc., but we don't know. And have you contacted Red Hat support, since you're PAYING FOR RHEL, RIGHT??

According to the man page the "attachment" has to be a FILE:
Did you do that?

Yes ehartman, it'a basic txt file.

@Tb0ne, i am trying to send a basic txt file using mailx. It uses smtp mail services.

Yes. OP what does your man mailx say, specifically about how to attach files?

Also, as has been asked, what exactly do you mean by "doesn't work"?
Are there any errors indicated in the maillog?

All of those commands look a little "off" to me. Are you creating a message body at all? Or did you leave that off for brevity? I'd expect to see something like:

or
if you don't need/want to include a message body.

Use "tail -f" on the /var/log/mail log file -- or "journalctl -af" (or similar) -- and watch what happens when you attempt to send the email with the attachment. Is it being accepted by the remote user's mail system? Or rejected?

Is your recipient able to receive attachments at all? Or are you sending one that's very, very large?

Pure ASCII, or in any other text encoding (like ISO-8859 or utf/ucs)?
That is: is it 7-bits characters only.
Otherwise: does your version of mailx know how to encode 8-bits byte (essentially binary) files into a mail?

In essence smtp is setup to use 7-bits chars only because of possible restrictions on "systems on the way".

Yes, ALL Mail systems use SMTP...that doesn't tell us anything. It's like saying "I use a computer for email"...very true, but kind of a given. To be more clear:

• Are you using postfix or sendmail on the back side of things??
• What version of RHEL?
• What you've ACTUALLY SEEN as the results of your tests. Does anything come through? If so, what? What do you see in the mail log files???
• Have you contacted RHEL support, since you're PAYING FOR RHEL????

If it's nothing but a text file, doing:
..is all you need. AGAIN, you will need some sort of relay host set up further upstream to route the message, but you've still not said anything about your environment. With no relay host or any sort of configuration on your server to process email, it's not going anywhere, and you've not provided any information we've asked for, other than saying it's a 'text file', and 'it doesn't work'. We can't guess.
